In a Distributed Control System (DCS), a deadband (also called hysteresis) is a designated range above and below an alarm setpoint. Within this range, small parameter fluctuations will not trigger an alarm, even if they approach the alarm limit. The deadband setting acts as a “no-alarm zone,” effectively preventing frequent alarms caused by minor, often […]
Transmitters such as pressure, differential pressure, and level transmitters are vulnerable to moisture ingress in humid environments (e.g., outdoor installations, damp workshops, underground pits, wastewater treatment plants). Water vapor can penetrate the housing, terminal compartments, or sensor diaphragms, leading to short circuits, signal drift, distorted outputs, or even total failure. To ensure reliable operation, a

In industrial settings, the wiring of instrument cables can often present challenges, especially when the cables are significantly longer than necessary and are coiled into loops at the installation site. Although seemingly a simple issue, coiled, excess-length instrument cables can introduce various problems that impact signal integrity, safety, and the overall functionality of the system.

The Modbus protocol, developed in the late 1970s by Modicon, is widely used for industrial automation and control systems. A key feature of Modbus is its straightforward data structure, centered around four types of data registers. These registers facilitate the transfer of both digital (binary) and analog data between different devices, such as programmable logic

In various industries, pipeline heating, or “tracing,” plays a critical role in maintaining the flow and stability of substances transported through pipelines. It prevents materials from freezing, solidifying, or deteriorating during transfer, making it especially valuable in fields such as petrochemicals, natural gas, chemical production, food processing, and pharmaceuticals. This article explores the primary types

Introduction High-temperature steam and dense chemical liquids are at the core of coatings, adhesives, high-performance lubricants, and specialty fluids. For chemical plants, processing these high-viscosity materials means mastering intense heat and shear forces to ensure stable quality and consistent production. This article explores cutting-edge process technologies to overcome common issues such as pipeline clogging and
In industrial automation systems, control valves often appear bulky and are perceived as relatively simple devices. However, they operate under complex process conditions on pipelines, and any malfunction can result in operational delays, system instability, and even environmental issues. Given their critical role in ensuring process control quality, proactive measures to extend their service life

When most people think about water purification, they picture filter cartridges, multi-stage filtration, activated carbon, or maybe UV lamps and softeners. In pharmaceutical manufacturing, however, this simplistic logic falls apart entirely. Take any vial of injectable solution. Even if the label lists nothing but “salt” and “water,” the process behind producing that water involves a
Are you experiencing erratic readings, unexpected zero drift, or sluggish response in your differential pressure transmitters with remote diaphragm seals? These issues often occur when large ambient temperature variations affect the capillaries and their fill fluid. In low temperatures, the fill fluid may thicken or even solidify; in high temperatures, expansion slows down response times
